Laser hair removal (LHR) is a popular, safe, and effective treatment for hair removal. The technology uses light to destroy the hair follicle and prevent new hairs from growing. Lasers are available in a variety of wavelengths (colors) that target different parts of the skin.
There are several types of lasers used for LHR, including fractional CO2 lasers, diode lasers, argon/krypton lasers, and solid-state lasers. For more information about Laser Hair Removal, you can explore this link.

Each type has its own benefits and drawbacks, so it's important to select the right one for your skin type and treatment goals. Before you begin your laser treatment, it's important to understand the basics of LHR: how it works, and what to expect during treatment and aftercare.
The laser destroys the hair follicle by heating it to temperatures above the point of combustion. The heat cause melanin to polymerize prematurely and break down strands of hair.
There are three types of lasers used in laser hair removal: erbium-doped yttrium aluminum garnet (YAG), neodymium-doped yttrium aluminum garnet (Nd: YAG), and titanium dioxide (TiO2) lasers. These lasers have different wavelengths that can remove different colors of hair.
The most common type of laser used for laser hair removal is the YAG laser. This type of laser has a longer wavelength than the other two and can remove color hairs more effectively than the Nd: YAG or TiO2 lasers.
Another factor that affects how well a person’s skin will tolerate laser hair removal is their Fitzpatrick level. A Fitzpatrick level is a measure of your skin’s elasticity and determines how sensitive your skin is to light and therefore, how good your results will be with a particular treatment plan.
